ABSTRACT
This case report highlights a severe eczematous rash manifesting broadly across the scalp, face, and neck of a 54-year-old female following a resolved herpes zoster infection. Notably, such cutaneous reactions post-varicella zoster virus infection, which may present weeks to years after the acute phase, have been documented but remain poorly understood in their pathogenesis. This patient exhibited a blistering rash diagnosed as shingles with overlying cellulitis, initially treated with valacyclovir and cefalexin. Upon returning with a diffuse rash post-treatment, further examination and tests led to a differential diagnosis that most closely aligned with eczema exacerbation with superimposed bacterial infection, confirmed by the presence of methicillin-resistant Staphylococcus aureus. Treatment encompassed intravenous vancomycin, ciprofloxacin eye drops, topical hydrocortisone, betamethasone lotion, and gabapentin, leading to substantial improvement. This case underscores the complexity of diagnosing and managing cutaneous reactions post-varicella zoster virus infection and suggests a multimodal treatment approach may yield favorable outcomes.
